Small/Painless Bump on the Shaft of My Penis

Hello all, as i wrote in the title, there is a small sized ( <- Same size of this as a bump), painless bump on the shaft of my penis, in the left side.

-> It has been there for like 1,5 weeks.
-> It is not squeezeable. (Only could squeeze very little yellowish thing when it appeared, but very little.) It has no head to squeeze it anyways. (So it doesn't look like a pimple.)
-> It has same color of skin, but a little pinkish.
-> It is totally painless and nothing uncomfortable with it.
-> There is a very very small black dot in side of it, but not sure, it is too small really, might be something else too.
-> It is totally combined with the skin and has no connection with the tissue under it.

I'm 17 years old and haven't had sex before, so what do you think it can be ?
Anyone else has experienced this ?

Squeezing it opens you up to infection. It's not a good thing to do.
It could be a pimple. If it is, it should clear up soon.
It could be a cyst. If it is, they are generally harmless. The way most men get rid of a cyst, is to have their doctor remove it. Otherwise, they tend to come right back.
Best of luck with it.
